Support Our Trails

Steep sections on Old Emerald Trail in Laguna Coast Wilderness Park are deteriorating from rain and heavy visitor traffic. To protect the trail and surround habitat requires intensive care.

In response, Laguna Canyon Foundation is pioneering rock-armored drains: dry-stone masonry construction that combines erosion control with tread fortification.

Our rock-armored drains withstand fast-moving bike tires, hiking boots, and water.

Rock Armored Innovation

Section d 3 before

Before

Steep trails cause major erosion and rutting. No fun to ride or hike + damaging to the environment.

After

Rock armored drains fortify the trail for feet and wheels + sustainably divert water off the trail. We fix the ruts in the trail and reclaim damaged habitat.

Help Build the Trail!

You can fund construction of a whole trail section, or contribute towards the next section up. Seven sections to go!

Thanks to a generous contribution, donations to the Old Emerald Project will be matched up to $10,000.

Give over $50 and receive a limited edition Laguna Canyon Foundation t-shirt as a thank-you gift.

In Spring 2025, we completed Sections D and I, installing rock armored drains, repairing tread, and naturalizing habitat.

While most technical work is completed by LCF staff, we provide opportunities for committed volunteers to build their trail stewardship skillset. In April, volunteers from REI joined us to do tread improvements and set “gargoyles” (off-trail boulders to help define the trail corridor). In May we hosted a rock skills workshop to share techniques with LCF long-term volunteers.

7 more sections need to be funded.
